Patient 2 suffered from a periacetabular chondrosarcoma and received wide resection by a type II, III internal hemipelvectomy through a combined ventral and dorsal approach and subsequent reconstruction with a custom-made pelvic implant articulating with a Zweymueller stem in 1992. The patient suffered from aseptic loosening of the implant six years after primary surgery, which was addressed by accretion of iliac crest autograft bone. A deep vein thrombosis was treated conservatively. The X-ray, which was taken 20 years after primary surgery, shows good hip function, and the patient can walk with a walking stick and has an HHS of 89 points.
